Well, I made a silly confusion mistake and thought the first line
was feedforward (and then equivalent to the bp~). But still, it
could be it for all I can tell. How can you actually see wether is
feedback or not?
stupid way: the coefficients are called "fb1" and "fb2"; "fb" is an
abbreviation for "feedback", so this might have put you onto the right
track.
complicated way: "last" and "prev" refer to past output samples (as
has been mentioned in other emails), and using old output to generate
new output is the definition of feedback.
